1 Claim.

This invention relates to a building structure and more particularly to the construction of a building wall.

The primary object of the invention is to make use of scrap materials such as those commonly found around saw mills, and like wood working establishments, and apply such scrap to a useful purpose.

Among its features, my invention embodies a building structure comprising inner and outer spaced walls, each of which is formed of blocks made from scrap lumber arranged in aligned relation and having aligning grooves in their upper and lower edges, said blocks also having grooves in their end edges perpendicular to but offset with relation to the first mentioned grooves, bonding blocks extending transversely between the inner and outer wall members and being positioned between the ends of the aligning blocks forming the wall members, said bonding blocks having grooves in opposite spaces adjacent opposite ends which are adapted to align with the grooves in the ends of the aligned blocks and bonding strips lying in the grooves and forming an interlock between the various blocks to hold the wall members in spaced parallel relation.

In the drawings:

Figure 1 is a fragmentary side view of a wall embodying the features of this invention.

Figure 2 is a top plan View of the wall illustrated in Figure 1,

Figure 3 is a fragmentary vertical sectional view on an enlarged scale through certain of the blocks illustrated in Figure 1,

Figure 4 is a transverse sectional view taken on the line 4-4 of Figure 2,

Figure 5 is a fragmentary perspective view of one of the corner members showing the manner in which the bonding strips are employed, and

Figure 6 is a perspective view of one of the bonding blocks.

Referring to the drawings in detail my improved building construction comprises an inner Wall designated generally Ill and an outer wall designated generally ll. Each of these wall members is composed of a plurality of aligned blocks I2, each of which is formed in its upper and lower side edges with longitudinally extending grooves 13 which are arranged in alignment with the grooves in the next adjacent block. Each block I2 is also provided in each end edge with a groove M which extends perpendicular to but is offset with relation to the grooves l3 as will be readily understood upon reference to Figure 2. Extending transversely between the wall members In and H formed of the aligned blocks 12 are bonding blocks l 5 each of which comprises a rectangular body having adjacent opposite ends and on opposite side faces grooves [B which when the bonding block is in position in the wall align with the grooves M in the ends of the blocks I2. Transversely extending grooves H are formed in the upper and lower edges of the blocks l5 and as illustrated in Figure 6, are offset so that when the blocks l5 are in position in the wall the grooves I! will align with the grooves l3.

In order to hold the blocks l2 of the wall members l0 and II in proper alignment, bonding strips H! are laid in the grooves I3 and are of such a width that they project upwardly into the grooves l3 in the bottoms of the blocks 12 forming the next adjacent course. Bonding strips [9 lie in the grooves l6 and are of such a width as to extend into the grooves l4 formed in the ends of the blocks l2 to form an interlock with the bonding blocks I5 and hold the parts properly assembled.

As illustrated in Figures 2 and 5, it is a simple matter to build a corner block through the simple expedient of sawing one of the blocks l2 in two and nailing or otherwise securing as at 2|] a block l2 perpendicular to the block [2 which has been sawed in two. The perpendicular block I2 is nailed or otherwise secured as at 2| to a block l2 forming the outer wall II and attached adjacent the outer end of the latter block as at 22 is a block [2 which lies in spaced parallel relation to the perpendicular block I2. It will thus be seen that a corner block may readily be constructed from the units above described by the simple expedient of sawing one of the blocks in two and nailing them together as illustrated.

From the foregoing it will be obvious that by the mere grooving of the waste blocks and cutting them to proper size, they may be usefully employed in the construction of a building having an inner and an outer Wall arranged in spaced parallel relation with suitable bonding blocks extending therebetween.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination, and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What I claim is:

A wall structure comprising inner and outer spaced parallel walls each formed of a plurality of aligned rectangular blocks having aligning grooves in their upper and lower side edges and having grooves in their end edges perpendicular to but offset from the grooves in the side edges, bonding blocks extending from wall to wall between the adjacent end edges of the aligned blocks of each wall, said bonding blocks being of uniform thickness throughout and having grooves in opposite side faces adjacent each end, said grooves aligning with the grooves in the end edges of the aligned blocksand each bonding block having transversely extending grooves in the top and bottom edges aligning with the aligning grooves in the top and bottom side edges of the aligned blocks, horizontal bonding strips fitted in the grooves in the side edges of the wall forming blocks and in the grooves in the end edges of the bonding blocks to hold adjacent blocks in wall forming alignment, and vertical bonding strips REFERENCES CITED The following references are of record in the file of this patent:
